Neil Lennon faces a pivotal selection decision as Ryan Christie returns for Celtic's clash with Kilmarnock.
The Hoops midfielder sat out the 3-2 Europa League win over Lille at Celtic Park on Thursday night.
In his place, fringe star David Turnbull staked a compelling claim for a regular starting berth with a hugely influential performance.
Ismaila Soro 's first Celtic start drew similar plaudits and he could keep captain Scott Brown out of the side for Killie's visit.
Nir Bitton, Hatem Elhamed and Olivier Ntcham all missed out in midweek with knocks and will be assessed while James Forrest remains sidelined after ankle surgery and Mikey Johnston is still building up his fitness.
Kilmarnock defender Clevid Dikamona is suspended after getting sent off against Hamilton last weekend.
But Stuart Findlay will return to the central defence following his red card the previous game.
Ross Millen, Gary Dicker, Chris Burke and Zeno Rossi will miss out again for Killie along with long-term absentee Jake Eastwood.
